Concrete Swimming Pools are constructed using Gunite or Shotcrete (sprayed concrete) or hollow concrete blocks. They are then tiled or lined. We explore the pros and Cons of this pool construction type:

Concrete is not forgiving of ground movement and can crack if stressed. So much so, that concrete pools built to British Standards and SPATA Standards are allowed to lose an average of 2000 litres of water a month.

The grout in tiles increases the surface area for bacteria to breed exponentially. This increases the volume of chemical required (chlorine or similar) and the amount of cleaning and scrubbing of the pools surface. Furthermore, tiles can easily pop off with movement.http://www.ehow.com/how_2157334_replace-swimming-pool-tiles.html

Compass Ceramic Pools

Pros

Our insulator (ceramic) is 1.5mm from the water so you do not waste money heating up the pool shell. We can also add as much insulation to the outside of the pool as you like.

The composite with which the ceramic is layered is flexible to ground movement and warranted against leaks through the shell for 50 years.

We lose zero litres through the shell from day one as it is made in an environmentally controlled factory (temperature and humidity)

Our shell finish is continuous, smooth and impermeable to bacteria. Reducing the need for chemicals to a minimum.

Con’s

We are limited to 32 shapes and sizes. Like a boat, they come from a mould.

We need access for an excavator, crane or helicopter to lower the pool into position.

In areas with a high water table all pool types can float if the pool is emptied, a one piece pool is however more susceptible due to its light flexible structure, we therefore have to add additional protection to stop this happening (hydrostatic valve and ground water protection)http://www.wisegeek.com/what-is-a-hydrostatic-valve.htm
